Key Features
- 【4-in-1 Passive Audio Combiner】 This device merges signals from up to four microphones, instruments, or line-level sources into a single balanced output. It’s the perfect solution for combining vocal groups, podcast mics, or multiple room mics when you need to feed them into one mixer channel or audio interface input.

- 【Pure Passive Parallel Circuit Design】 Operating without external power, it uses a high-quality parallel connection design with transformer isolation to sum signals cleanly. This ensures minimal noise, low signal loss, and preserves the balanced audio quality from all connected sources.
- 【Professional-Grade Build for Reliable Performance】 Housed in a solid aluminum alloy chassis that shields against interference, it features gold-plated copper connectors and a secure internal PCB. Built to deliver stable, noise-free performance in demanding studio and live sound environments.
- 【Simplify Your Audio Workflow】 Ideal for musicians, podcasters, and engineers who need to merge multiple audio sources. Use it to combine backing vocal mics on stage, multiple podcast host mics for a single computer input, or to sum auxiliary mics when your mixer’s inputs are fully occupied.
